Of course you don't count them. When is a fan not a fan? When Jaydee wants them not to be. How silly could you be? A fan is a fan. Because they are electro-mechanical devices they fail. When they fail, sometimes the things they are cooling get hot and die. Sometimes when things get hot and die they take other things with them. The power supply could take out motherboard or anything connected to it. The chip set could take out the CPU, memory, or PCI bus cards. They could just get their lifespan significantly shortened. Or if you're lucky they could just shut down (assuming of course that they are thermally monitored!). That's why there are fans there in the first place (is this a new concept to you?). That is why most fans in modern computers today, even the ones in power supplies and on chip sets, have tach outputs to monitor. Unless of course you're Jaydee. Then they don't count.
